When we see a flower, we sense the flower is outside and our eye consciousness is inside; however, this is the perception of the mental or sixth consciousness, not the eye consciousness. What is eye consciousness? For instance, at the time we see an object, that “seeing” is in itself eye consciousness. There is no other eye consciousness besides this. Perhaps someone thinks eye consciousness is likened to light, which shines on a certain object and allows it to be seen. This is not the case. When an object appears before our eyes, eye consciousness is that which sees it instantly in its entirety, i.e., has a sense of the object.
